PATENT GFFICE IVIASSACHSETTS, .ASSIGNOR TO UNITED SHOE JERSEY MACHXNE SHAPENG`UPPEFJS OVER LASTS Application filed; ,August 28, 1930. Serial No. 478,423.

rlhis invention relates to machines for use in the manufacture of shoes for shaping uppers over lasts, applied to a machine for lasting shoesnprogressively by pulling the upper, laying it inwardly over the insole and fastening it in different locations successively along` the edge of the shoe bottom, usually at the opposite sides of the slice, as the shoe is presented by `f the operator in dillerent lasting positions, the

machine shown having means for fastening the upper' to a lip or rib on theinsole (hereinafter referred to as the lip). lt .is to b` understood, however, that in its more general aspects the invention is not limited to niachinesof the particular type illustrated noi' to machines for operating upon shoes'of that type in Which the insole is provided With a lip. 1 Machines of the above-mentioned charac ter are each provided with a shoe rest against whichthe operator holds the bottoni of the shoe and which supports the shoe against the pull ofthe gripper on the upper heightivise of the last, this shoe restalso assisting by its engagement with the insole in preventing displacement of the slice laterally or in a direction transverse to its height by theforce applied in pulling or laying the upper inwardly over the insole, but permitting the shoe to be moved readily from one lasting position to another. ln operating` upon shoes in which the insole has a lio on its outer face. such as Welt shoes, the shoe rest engages the inner side of the lip, and accordingly its action in preventing such displacement ofthe shoe is due largelyto its pressure aga-inst the lip.

An' object of the present invention is to provide improved means for controlling the shoe in machines of the general class referred to, and especially for holding the shoe against displacement bythe force applied in pulling` or laying the upper inwardly over the shoe bottom. For the purpose in view the construction shoivn comprises means Which is movable intermittently into and out of engagement with the insole in time relation to the successive lasting operations on the shoe and acts in conjunction with the shoe rest to resist the force tending to displace the and is herein illustrated asr shoe as above desc 1iloed. More particularly, this mechanism, as illustrated, comprises a member formed topenetrate the insole and controlled by the gripper-operating lever, so

that the member is moved into operative position as the gripper is moved toward the shoe preparatory to the gripping of the upper and is Withdrawn from operative position as the gripper is retracted after its release of the upper, thus permitting the shoe to be readily advanced to the next lasting position. lt will be evident that as applied to a machine in which the shoe rest engages a lip on the insole as hereinbefore described, such 'additional shoe-controlling mechanism serves to lessen the strain on the insole lip due. to the pressureof the lip against the shoe rest and thus to insure against distortion of the lip or such displacement of the shoe relatively to the shoe rest as to result in improper or insecure fasteningof the upper if the lip is formed of unusually flexible or yielding material.

rlhe novel features of the invention Will now be more particularly described by reference to the accompanying drawing-and thereafter pointed out in the claims.

In the drawing,

Fig. 1 is a view, partly in right-hand side elevation and partly in section, of a portion of a machine in Which the invention is embodied;

Fig. 2 shows a portion of the structure in left-hand side elevation; i

Fig. 3 is a View illustrating the operation ofthe machine on a shoe, and

Fig. et is a viev7 at right angles to Fig. 2 showing more clearly the shape of the additional shoe-controlling member.

The invention is herein illustrated as applied to a machine constructed as disclosed in Letters Patent No. 1,796,451, granted upon an earlier application of mine on March 17, 1931, and accordingly only such parts of the machine as it is necessary to refer to for an understanding of this invention are hereinachine includes in its organization a shoe rest 10 which is arranged to engage the bottom` of a shoe presented and held by the operator in different positions successively for in shown and Will be described in detail. The y the progressive lasting of the shoe along each of its opposite sides. As herein illustrated the shoe rest is constructed and arranged to engage the inner side of the lip a of the i insole to determine the lateral position of mentioncd Letters Patent, the gripper is i moved heightwise of the last by a two-part updraw lever comprising a front part 1G connected to the gripper and fulcrumed at 18 on the head of the machine, and a rear part 20 pivoted at 22 on the rear end of the front part 1G and operated by a cam 24 on a cam shaft The two parts of the updraw lever are further yieldingly connected together through a spring 28 so as to permit relative movement between them in response to resistance of the upper to the pull of the gripper thereon. The gripper 12 is pivotally mounted on the front end of the part 16 of the updraw lever for swinging movements inwardly and outwardly over the shoe bottom, these movements being controlled by a rod 30 and a bell-crank lever 32 which is connected to the rod and is operated by a cam on the cam shaft 26. Aftorsion spring 36 acts on the lever 32 to impart to the gripper movement topull the upper yieldingly inward over the insole, and the cam 34 moves thev gripper in the opposite d1- rection against resistance of the spring.

In operation the gripper is moved downwardly toward the bottom of the shoe by downward movement of the part 16 of the npdraw lever and is moved outwardly toward the edge of the shoe bottom by the cam 34 preparatory to the gripping of the upper in each lasting location. Thereafter the gripper is moved upwardly by the updraw lever to pull the upper heightwise of the last, the spring 28 being compressed more or less by reason of resistance of the upper to the pull of the gripper, and is then Amoved inwardly over the shoe bottom by the spring 36 under control of the cam 34 to pull the upper inwardly over the insole. As the gripper is thus operated to pull the upper inwardly, an over-laying member 38, which in the machine illustrated consists of a stapleguiding nozzle, is moved inwardly over the shoe bottomrin a downwardly inclined direction and acts on the upper to lay it over and down upon the insole and against the outer side of the insole lip. Substantially at the end of the inward movement of this member the gripper releases the upper, whereupon the front portion 16 of the updraw lever is swung upwardly by the spring 28 to carry the gripper farther away from the shoe bottom. Thereafter a staple is driven from the member 38 through the upper and the insole lip and is clinched on the slice rest member 10 to fasten the upper to the lip.

It will be evident that as the upper is pulled inwardly over the insole by the gripper and is additionally forced inward by the overlaying member 38, considerable force is applied to the shoe tending to displace it laterally or in a direction transverse to its height. The shoe is normally held against such displacement by engagement of the shoe rest 10 with the lip of the insole and in part also by such friction as there is bctween the insole and the lower end face of the shoe rest due to the upward pressure of the shoe against the shoe rest as the operator supports and holds the shoe. To assist further in controlling the shoe, and thus to insure against any possibility under some conditions of distortion of the insole lip by too great a. strain thereon or of such displacement of the shoe relatively to the shoe rest as to result in the driving of a staple or staples in improper relation to the lip, as welles to relieve the operator of the necessity of exercising any special care in holding the shoe in such manner as to guard against these results, the machine herein shown is provided with a member 40 which is moved intermittently into and out of engagement with the insole in a location near the shoe rest 10 and has sharp prongs adapted to penetrate the insole. The member 40 has an up wardly extending shank portion 42 which is slidingly mounted in a bracket 44 fast on one side of a holder 46 to which the shoe rest 10 is secured. The movements of the member 4() toward and from the shoe are effected by the front portion 16 of the updraw lever. For this purpose the upper end of the part 42 is connected by a flexible spring coupling 48 to the lower end of a rod 50 which extends upwardly through an opening formed in a stud 452 carried by the part 16 of the updraw lever.

Between the stud 52 and a clamp 54 which is fast on the rod 50 is a spring 56 through which downward movement is imparted yieldingly to the rod 50 by the updraw lever to force the member 40 downwardly into contact with the shoe. Nuts 58 on the'upper end of the rod 50 provide means whereby lthe stud 52 lifts the rod as the part 16 of the lever is moved upwardly, thereby withdrawing the member 40 from engagement with the shoe. It will be understood that the member 40 is thus forced downwardly into contact with the insole as the gripper is moved downwardly toward the slice bottom preparatory to the gripping of the upf per in each lasting location, the spring 5G being compressed more or less during further downward movement of the part 16 of the updraw lever after the member' 40 has engaged the insole. Thereafter the spring 56 serves to maintain the member yieldingly in its operative position during such upward movement of the part 16 of the lever as takes place in pulling the upper heightwise of the last, and it is only upon release ofthe upper by the gripper substantially at the end of the operation of laying the upper inwardly over the insole that the member 40 is withdrawn from engagement with the insole by the fur- Jther upward movement ofthe part 16 to its starting position. It will thus be seen that during the time that torce is applied to the shoe tending to displace it laterally, the member l0 acts conjointly with the shoe rest l() in holding the shoe against such displacement, and the member is thereafter withdrawn from engagement with'the insolel to permit the shoe to be readily advanced by the operator to the next lasting position. By its holding action on the shoe the member 40 relieves the insole lip of any excessive strain such as might distort it or result in improper displacement of the shoe it the lip were made of unusually liexible or yielding material, and at the same time relieves the operator of the necessity of exercising as much care as he might otherwise have to exercise under such conditions in holding the shoe in such manner as to guard against excessive strain on the lip.

While the inventionv is herein illustrated in its application to a machine for operating` on shoes in which the upper is fastened to a lip on the insole, with the special object of avoiding excessive strain on the lip, it will be evident that the nevel means provided for controlling the shoe is not limited in utility 'to an organization of that particular character.
